NovaTorque PremiumPlus+®

3HP & 5HP Electronically Commutated Permanent Magnet Motors

The Next Leap Forward in Electric Motor Efficiency

One of 2011’s 100 most technologically significant new products according to R&D magazine

NovaTorque’s mission since its founding has been to both build a successful enterprise and to make a real difference in the world. Nearly half the electricity consumed in the US is used to turn electric motors. Even modest improvements in energy efficiency lead to large reductions in energy bills and carbon emissions.

• Mission: Cost-effective energy efficiency

• Focused on variable speed air handling applications

• Delivering a 30% to 50% reduction in wasted energy

The metric that has always driven NovaTorque’s motor design has been to obtain the highest efficiency per dollar of motor cost. Anyone can build a high efficiency motor if they use expensive materials and costly manufacturing tolerances and processes. It is also easy to build a low-cost motor with low efficiency. The real challenge is to build a high efficiency motor with a low manufacturing cost. To make the kind of environmental impact we hoped to achieve when NovaTorque was founded, we knew this new technology would need to become nearly as ubiquitous as the AC induction motor is today. And for that to occur, we needed not only to achieve our efficiency goals but also to do so at a cost and price point that would encourage widespread adoption. Our goal has been to create a motor both higher in efficiency and at comparable volumes, comparable in costs.

John PetroNovaTorque, Founder and CTO

We bring a level of energy efficiency that cannot be economically achieved with induction motor technology, and we do so at a first cost price that is comparable to the induction motor.

The cost of powering an electric motor over its useful life is about 50 times the cost of the initial purchase. In typical applications such as powering fans or blowers in a commercial HVAC system, applying a NovaTorque motor versus the most efficient induction motors available today can reduce the annual energy bill associated with powering the motor by 5 to 15%, year after year. That’s huge.

NovaTorque PremiumPlus+® 3HP and 5HP Electronically Commutated Permanent Magnet Motors

Designed for variable speed air handling applications

The innovative features of the NovaTorque® design result in a device superiorin both efficiency and performance, when compared to its NEMA Premium® efficiency induction motor competition. Importantly, the NovaTorque motor is also cost-competitive. The unique conical rotor and stator geometry and its concentrated axial flux path enable the use of low-cost ferrite magnets to deliver rare-earth-like motor performance. And, the NovaTorque motor maintains its high efficiency over a very wide speed and/or load range.

30% to 50% Reduction in Wasted EnergyIn typical variable torque, variable speed, applications, such as fans and pumps, NovaTorque motors have proven to reduce energy losses (energy that performs no useful work) by 30% to 50%, reducing energy costs by 5% to 15%.

While NovaTorque motors enjoy a commanding efficiency advantage at rated speed and load, most applications involving the use of variable frequency drives operate at less than rated speed much of the time, making high efficiency over a broad speed range especially important. Further, many motors are oversized for their application, again making high efficiency over a broad load range important. Whereas the efficiency of an induction motor falls off dramatically as the speed and/or load declines, NovaTorque motors maintain their high efficiency over a very wide operating range. This further improves their advantage when the motor is operating at lower than rated speed and/or driving less than full rated loads.

Efficiency comparison of NovaTorque’s PremiumPlus+® 3HP motor with the leading NEMA Premium® 3HP induction motor and the prior Epact standard induction motor. All motors were operated with the same variable frequency drive.

Optional long life shaft grounding mechanism protects bearings from electrical discharges.

Stator

Standard NEMA mounting and shaft dimensions.

Use of permanent magnets to produce magnetic field in the rotor inherently saves energy when compared with the electrically induced magnetic field in an induction motor rotor.

Unique conical air gap mating of stator and rotor maximizes surface area, concentrating flux, allowing for use of cost effective ferrite, versus rare earth, magnets.

Interior permanent magnets (IPM) further focus flux while increasing saliency for improved sensorless motor control.

Axial flux path allows for use of grain oriented steel, minimizing eddy current losses.

Axial orientation of field poles allows for use of bobbin wound coils, eliminating the wasted material and energy associated with end turns

Due to higher efficiency, motor runs cooler, extending motor life. Additionally, due to the positioning of the windings, the heat that is generated is more efficiently dissipated.

Oversized bearings for longer life.

Dual conical-shaped rotors.

As with all permanent magnet motors, NovaTorque motors require electronic commutation and cannot be run off the AC mains as induction motors may. A variable frequency drive (VFD) is required.

Specific VFD Features Required

While most major VFD manufacturers have introduced Permanent Magnet (PM) motor support, not all models include this. A list of compatible drive brands are included below. Contact NovaTorque Applications Engineering for details on VFD compatibility and parameter setup.
